This method involves the successive multiplication of the digits by the given base.

This is another method of converting other bases to denary or decimals system is by repeated or successive multiplication. i.e.ġ2203 = 1 x 33 + 2 x 32 + 2 x 31 + 0 x 30 - Expanded formĬonversion by repeated/Successive Multiplication The powers correspond to the place values of the number and they show the order of the digits. System) but can also read as “two one to base 3”. Note that the above expression as twenty eight base eight, because this is the language in the denary Reads as two, five to base 8 meaning 2 x 81 + 5 x 80 that is the 2 eights and 5 ones. In order to differentiate the numbers in different bases we use subscript notation. These are the current conventional notations. The number of unit used in the system is always equal to the base.ĭecimal/Denary Base 10-Digits Quinary Decimal/DenaryBase 10-Digitsįor 13, E for 14, F for 15 since these numbers are regarded as single digits in the hexadecimal scale.In the hexadecimal base (base 16) system the letter A represents 10, B represent 11, C represents 12, D It is possible to use any number as a base in building a numeral system. If the data itself is unique per row, you could generate the unique id from a sha of the concatenated row value (ie join all the values in the row together and then perform a sha1() on the string and split however you'd like).Topic: CONVERSION FROM OTHER BASES TO BASE (10) TEN You could then generate a unique id from that autonumber if you so wanted to (for example like the answer mleko gave). The below is for if you are not using a back end database:įor example if you have a table that might contain rows with the same data, you would need to add a column that is unique - the simplest being an autonumber of some sort (eg, 1,2,3,4,5 and so on). If there is a database involved anywhere in the back end, i'd use the database's unique key field and then use that to generate the unique id. Your question is a little ambiguous in that you're not clear in if this unique id is unique for data that might be the same in different rows or if its unique data for any row or why you really need a unique ID formatted like a MAC address as opposed to just a number that increments.
